Investigation of the Role of Organic Acids on the Phosphorus and Zinc Uptake by Corn in Calcareous Soils by Using 32P and 65Zn Radioisotopes [PDF]
To investigate the effect of oxalic and citric organic acids on the uptake of Phosphorus and Zinc by corn (Zea mays L.), an experiment was conducted by the use of radioactive potassium phosphate and zinc sulfate fertilizers in microcosm and greenhouse ...

The Deafness-Associated Mitochondrial DNA Mutation at Position 7445, Which Affects tRNASer(UCN) Precursor Processing, Has Long-Range Effects on NADH Dehydrogenase Subunit ND6 Gene Expression [PDF]
The pathogenetic mechanism of the deafness-associated mitochondrial DNA (mtDNA) T7445C mutation has been investigated in several lymphoblastoid cell lines from members of a New Zealand pedigree exhibiting the mutation in homoplasmic form and from control

A biosynthetic method for the preparation of high specific activity 32P-labeled phospholipids
32P-Labeled phospholipids with specific activities up to 400 mCi/mmole as well as [32P]CDP-choline were prepared by cultivation of mouse fibroblasts or mouse Ehrlich ascites cells in the presence of [32P]orthophosphate.

Phosphoproteins and protein-kinase activity in isolated envelopes of pea (Pisum sativum L.) chloroplasts [PDF]
A protein kinase was found in envelope membranes of purified pea (Pisum sativum L.) chloroplasts. Separation of the two envelope membranes showed that most of the enzyme activity was localized in the outer envelope.

The chloroplast import receptor Toc34 functions as preprotein-regulated GTPase [PDF]
Toc34 is a protein of the chloroplast outer envelope membrane that acts as receptor for preproteins containing a transit sequence. The recognition of preproteins by Toc34 is regulated by GTP binding and phosphorylation.

Phosphorus utilization by corn as affected by green manure, nitrogen and phosphorus fertilizers
The objective of this work was to evaluate the utilization by corn plants of P from triple superphosphate fertilizer labeled with 32P (32P‑TSP), and of P from soil as affected by N rates and by the green manures (GM) sunn hemp (Crotalaria juncea) and ...

Regulation of intracellular cyclic GMP concentration by light and calcium in electropermeabilized rod photoreceptors. [PDF]
This study examines the regulation of cGMP by illumination and by calcium during signal transduction in vertebrate retinal photoreceptor cells. We employed an electropermeabilized rod outer segment (EP-ROS) preparation which permits perfusion of low ...
